More than 100 Saudis have been repatriated to Saudi Arabia from Guantánamo. The United States has trusted the Saudis to rehabilitate these former detainees and make sure they do not return to the battlefield. But the New York Times has now reported disturbing new evidence that the Saudi program is not going as planned.

Said Ali al-Shihri, a former detainee at Guantánamo, disappeared from his home in Saudi Arabia after spending months in the Saudi rehabilitation program. He is now the deputy leader of al Qaeda’s Yemeni branch, which most recently executed the bombing on the American Embassy in Sana in September of 2008. That attack killed 10 civilians, as well as six terrorists, and al-Shihri may have played a direct role.
